Hey, would you be able to go through mock sets? There are a lot of videos of walkthroughs of current past papers - however no videos going through mock sets.
because it is a vertical force, if it is directly vertical it will have 0 force in the i direction (horizontal) therefore there is a only a j component and so we do not have to resolve this.
just a suggestion is to maybe have the qs and your working side by side, because it gets confusing once the info from the qs isn't on the screen anymore and it's jus ur working
no need for a prediction stats and mechanics is small every topic will come up for mechanics (general suvat,ladder problems,projectiles variable accceleration,pullies and slopes )those are the only topics that can come up and most of the time mechanics is like 5q and exactly the same with stats
For 9a how is the normal reaction force being perpendicular justified by the fact that the peg is smooth. Even if there’s a rough peg then surely there’s still a reaction in the same direction.
I remember for the projectiles Q when I did it I didn’t include the angle either and I was really annoyed cos I’ve never been taught we have to put an angle too cos they didn’t even ask for it 😂
It's a log graph. log(y) against log(x) has a stronger linear correlation than between y and x. It makes more sense if you look at it on a graph. you'll find that the graph of y against x has a gradual slope, like an exponential, and will have a general equation of something like y = ax^n. if you take logs of both sides, you can rearrange it into the form: log(y) = nlog(x) + log(a). This closely fits the general equation for a linear graph, which is y = mx + c. So, if you let log(y) be your y value, log(x) be your x value, n be your gradient, m, and log(a) be your y-intercept, c, you"ll have a graph of a straight line passing through the y-axis at y = log(a). Essentially what the question is asking is, how does the linear correlation between log(y) and log(x) compare to between y and x? If the correlation between log(y) and log(x) is stronger, it suggests that a non-linear model, such as an exponential one like y = ax^n, will make more sense.
You resolve horizontally and vertically, as opposed to parallel and perpendicular to the ramp. You use Ncosθ because that is the horizontal component of N, not the parallel component as the parallel component is 0, and you use 20g because the weight of the ramp acts exactly vertically.
I’m really sorry i still don’t understand. He broke down both 20g and N into Horizontal and Vertical Components but he never used the Hori/Vert Components of 20G when resolving but used N’s Components. Why?
Hi, Mr Astbury,I just came across a Normal distribution hypothesis exam q and do not understand even when I read through the mark scheme. It's Edexcel Statistics 3 June 2015, Question 5: (The volume, B mL in a bottle of Burxton's,......) May you walk it through? Many thanks.
watching through all of these in preparation for Paper 3 on Thursday
yeah same
@@sebstephenson5971 same
Same here

early bird catches the worm. respect to all those watching this whilst every1 sleeping
Thanks for this. Would you be able to do the mock papers as well?
Would you be able to an applied madas paper sir? Thank you
Landed just in time! 😄 hope you find useful. ruclips.net/video/2p35BI5RaRc/видео.html
Sir I swear to god I'm gonna cry you're the goat 😂
Thanks! 🙌

@manimoneytv okay thanks. What about 1 and 2?
for qs 7a, how comes u're allowed to turn the i and j components into fractions?
ruclips.net/video/6KBJrsO3pno/видео.html
this guy explains it better for that question
i have absolutely no idea at this point just memorise every step for q7
because he is using the gradient equation of change in y (or j in this case) / change in x (i)
gonna be telling s to go do one when working out suvat thanks to you LOL
Absolutely!
Could you also do the Pearson mock sets
gurjbob?
for question 4b, why do you do force components for the 2 you have done but not for the reaction force at A? Thanks so much, video is great!
because it is a vertical force, if it is directly vertical it will have 0 force in the i direction (horizontal) therefore there is a only a j component and so we do not have to resolve this.
Thanks for your videos, officially finished A-Level Maths!!
just a suggestion is to maybe have the qs and your working side by side, because it gets confusing once the info from the qs isn't on the screen anymore and it's jus ur working
also, would appreciate if you showed how to do stuff on the normal calculator
for my suggestion, u did it for qs 9 of mechanics
Thanks for the suggestion. The feedback is really helpful. Video on the classwiz calc here ruclips.net/video/u3BeOXhBm6E/видео.html
Are you going to do a prediction for stats and mechanics? Your previous predictions for paper 1 and 2 were pretty accurate.
no need for a prediction stats and mechanics is small every topic will come up for mechanics (general suvat,ladder problems,projectiles variable accceleration,pullies and slopes )those are the only topics that can come up and most of the time mechanics is like 5q and exactly the same with stats

Could you post a video on how to use the casio fg50 for stats the same way you did it for pure ?

Would it be possible to get a Hypothesis Testing video? Its the only thing really bugging me about paper 3
how? what about mechanics ?
Its calculator work just like type stuff and get answer and write “insufficient ebidence reject Ho because blah blah”
For question 3b it asks about non linear so why do we talk about strong correlation isn’t that linear?

@@milliespencer634 yep thanks makes sense
That's why you're the GOAT
thank you, legend
1:17:14 Why did you use 20g and not 20gcosØ when resolving vertically because you used NCosØ
You resolve horizontally and vertically, as opposed to parallel and perpendicular to the ramp. You use Ncosθ because that is the horizontal component of N, not the parallel component as the parallel component is 0, and you use 20g because the weight of the ramp acts exactly vertically.

@@MrAstburyMaths incredible thankyou sir
in question 3 why are we allowed to start with the form? i thought we always had to show a method to get to the form
How come theres no horizontal reaction force at point A on the moments question (Q9)?

If it's from 2015 you might not understand it because the spec has changed since then.

Please do 2020 and 2021 aswell
I’ve done them already, check my earliest videos 👍
Thanks👍
for 9a) but in ladders the reaction at the top is not perpendicular to the ramp even when the wall is smooth, so i am a little confused
good luck this summer!
Nooo don’t private the applied video it was so good
Audio was messed up. Trying to fix it and upload later tonight
How do you do 4bi on a fx-991EX?
Check out this fx-991ex video ruclips.net/video/u3BeOXhBm6E/видео.html
where does it say the set is from may to October in question 2??
you are meant to now that as those are the only dates recorded for the large data set
That’s LDS knowledge
